Smart EMS

Smart EMS — Your sun, battery and EV charger finally on the same team. You've collected the pieces: solar panels on the roof, maybe a home battery, an EV charger in the driveway, a smart meter watching the grid. Each one is clever on its own. Together, they spend most of the day quietly competing. Your battery discharges into the kettle while the sun is filling the panels. Your car charges from the grid while the battery sits half-full. At five o'clock, when prices spike, the battery you were saving has already been spent. Smart EMS is the conductor that makes them play together. One Homey device — using the apparatus you already own — watches the live energy balance and decides, fifteen seconds at a time, where the next kilowatt-hour goes. A day with Smart EMS It's Sunday morning. The sun is up, the car is in the driveway, the kettle's on. Smart EMS sees the surplus, sends it straight to the car. By midday the car is comfortably topped up, so the surplus flows into the home battery instead. By three o'clock the battery is full enough to cover the evening, so the rest goes to the kettle, the heat pump, the dishwasher — anywhere but back to the grid. Six o'clock arrives, prices climb, and the battery you've been quietly filling all afternoon starts paying you back. You haven't touched a setting. You haven't opened a dashboard. The house just runs. Monday morning you've got a long drive ahead. The night before, you tap Force EV charge. Smart EMS picks the cheapest hours of the night to bring the car to full. Tuesday you're working from home and the sky's grey all day — no surplus, no problem; the battery covers the load and Smart EMS just keeps a tally for tomorrow. That's the entire user experience. Set it up once, watch a sunny day, and forget about it. What you get One tile, one decision. A single Grid Aware EMS device that summarises what's happening right now — in plain language. "Charging EV from solar". "Topping up battery". "Holding for evening prices". No graphs to interpret. No modes to learn. Force buttons for the moments you do want control. Top up the car overnight, fill the battery before a price spike, skip a day for the holidays. Press the button. The strategy bends around you. Widgets that show the story of your day. A 24-hour view of where every kilowatt-hour went. An hour-by-hour zoom into any moment of the last day. Coffee-in-hand morning entertainment. Sensors that play nicely with your flows. Surplus, battery flow, car charging, mode, and a dozen more — all available as Homey signals you can graph, dashboard or react to in your own automations.
